[edit]Those bastards at Fox (Fox8 here in Australia)!!
Thursday night -- 2 hours of 24 -- one episode without commercials, 5 minutes of break then another full episode without commercials. (the latest season -- just started three weeks ago)
It's reaching saturation. I have to Tivo it (Foxtel IQ it) to catch it, but after two hours I have to go through 6 days and 22 hours of withdrawal before the next pair.
2 hours of 24 is more than twice as strong as a single hour at a time...
[edit] Just to clarify, by 'last' season, I mean the one where Palmer is assassinated and Bauer turns out to be not dead after all.
